bin cheng <amker at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2018-08-23 Ever confirmed|0 |1 --- Comment #3 from bin cheng <amker at gcc dot gnu.org> --- This was first introduced enabling loop nest distribution. Reason is we compute wrong dependence direction for two partitions. I suspect it kind of relates with PR85804 which in essence a fusion issue, while this is distribution. Will keep investigating.
